Abstract
The present invention provides a laser engraver for
engraving a pattern on a workpiece. The pattern is
established on the workpiece by using a X-Y assembly(32a,32b) to
move a laser beam in two dimensions relative to the
workpiece. The X-Y assembly employs a X proportional-
integral-differential (PID) controller (34a) and a PID (34b) to
generate control signals for moving the X-Y assembly.
The PIDs generate the control signal based upon the
current position of the laser beam and a target position
for the laser beam. The current position is provided by
encoders (36a,36b) operatively attached to motors (38a,38b) that, in turn,
move mirrors (44a,44b) that direct the laser beam to the
workpiece. The depth of cut is, preferably, controlled
by using the integral of the difference between the
position of the laser beam as it is moved by the X-Y
assembly and a reference position. Alternatively,
proportional control based upon the absolute difference
between the position of the laser as it is moved by the
X-Y assembly and the reference position can be utilized.
